只是对你的做法有点异议：
首先，在美国，不能对陌生人突然来这么长个讲演，人家不知道你到底要干什么，想走又不礼貌，只好耐心等你说完。对不认识的人，无论说什么，都要简单明了。
我为什么当时没解释？因为我坐得比较远，并且开始吃东西了，我看到他拿了面包就走了，我当时也愣了，后来看她又烤了面包，就不想跑过去解释了。如果当时我在旁边，肯定会替他道歉，但是不会说很多，只是说：“Sorry, his first time here, he didn't know he took your bread”，她肯定明白的。
第二，那段英语有一点语法方面的flaw:
Sorry the guy is the first time to be here. ---- the first time 不能这么用，应该是 Sorry, it is the first time for him to be here, 或者: Sorry, it's his first time here, ...
He is not familiar with this kind of way for breakfast. ---- ‘this kind of way for' 没见过这个用法，可以说‘he is not familiar with this kind of breakfast'，或者 he doesn't know much about such kind of breakfast 可能更常用一些。
He accidentally took your bread. ---- ‘accidentlly'太重了，he took your bread by mistake 更合适一些。
The Lady would usually say: "If it is ok, I know he must be very hungary." ---- 'If it is ok' 不太清楚想说什么，你是想说‘It's ok，I know he must be very hungry’?
当然，我也不是说自己都对。如果挪威星能帮你就更好了。
